As unmanned aerial systems (UAS) become ever more prevalent and diverse in their application (control line inspection, package delivery, surveillance, etc.), their inclusion in the national airspace is unavoidable. New use cases for these vehicles are being formed every day, and the variety of their design forms (fixed wing, rotorcraft, quad-copters and greater, tail sitters, etc.) and sizes (0.55 to 10’s of thousands of pounds) will prove challenging to certify. To meet the stringent requirements of both the government and public expectations of safety, a robust procedure must be established through which the vehicle’s handling and flying qualities can be determined. In the realm of manned vehicles, this has been accomplished through the application of longstanding requirements on vehicle performance, dynamics, and controllability as defined by the Federal Aviation Regulations in the civilian world or standards, such as MIL-STD-1797, in the military domain. For military rotorcraft, a mission-oriented approach has been in usage for decades, as defined in ADS-33E-PRF, and is well accepted by the rotorcraft community. To address the issue of UAS certification, a team led by Systems Technology Inc. developed a process to guide the UAS community through the handling qualities evaluation of a UAS. Given the current and expected diversity in vehicle type, size and mission, the mission-oriented approach was selected for this application. A demonstration catalog of candidate mission task elements (MTE), specific tasks with well-defined evaluation processes and criteria, have been defined and flight tested using a representative UAS. The results of these evaluations are presented herein.
